PIANO-LAMP.

T0 (filer/1.0m it may concern Be it known that I, ALLAN FRAsn a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Piano-Lamps, of which the following is a specification. V

This invention relates to a lamp which is more particularly designed for illuininatmg the space in front ofa piano so .that'the key board and music are clearly visible andit has for its object the production of a lamp. of this character which is .comparatively simple and inexpensive in construction, which can beeasily and conveniently'ap plied to the fronts of upright pianos which may vary in thickness and construction, and which is neat and ornamental so asnot to detract from the'appearance of thefpiano upon which the same is mounted.

in the accompanying drawings: F gure 1 is a fragmentary vertical section of ,a;piano front and lid showing my improved lamp" applied thereto. Fig. 2 is atop plan view of the same with the lid omitted and the hood of the. lamp shown'partly; in section, Fig. 3 is a perspectiveview, of the lamp viewed from its under side and showing the lighting element omitted. Fig. 4: is a fragmentary verticalsection, on an enlarged scale, taken on line l 4,,Fig. 2. v

Similar characters of reference indicate corresponding parts throughout the several views. 7

Although this lamp may be applied to pianos which may vary inconstructlon the same is shown in Fig, l'applied toan upright piano the casing of which has an upright front or board 1 which can be tilted more or less in order 'to support the music thereon in a more or less inclined position" and a normally horizontallid or top 2 which is movable vertically toward and front board. g Y

The piano lamp which embodies my 1mprovements is adapted to be mounted upon the upper edge of the piano front and below the lid and in its preferred form the same is constructed as follows:

The front of the lamp has the form of a hood which is preferably constructed of sheet metal and comprises a cylindrical body 3 which is normally arranged horizontally and provided in its underside with a longitudinal light outlet opemng 4 and two cirfrom the Mamba. '7, 1920.

Application filed February 23,1918. Serial No. 218,611."

cular heads 5, (iapplied to opposite ends of this body. Arranged lengthwise within the hood is the lighting element which in this instance consists of an electric light bulb 7 which'is detachably connected with a socket or base 8 arranged within the hood and mounted on one of the heads of the hood, for instance the head 5 at the left hand end of the same. The cord 9 containingthe electric conducting wires for the lamp filament is preferably extended laterally through one side ofthe head 5, and the socket 8 is provided with an internal switch for opening and closing the circuit of this lamp which switch may be controlled by means of a pull chain 10 connected with the switch in any suitable and well known manner.

My improvements relate more particularly to the mounting whereby this hood is detachably supported on the piano front and the heat of the electric bulb is prevented from being transmitted from the hood to the finished jor varnished surfaces of this front so that scorching or marring of the same is avoided. In its preferred form this mount ing is constructed as follows:

In rear of the hood is arranged a bracket which comprises two longitudinal front arms ll, 11 project ng rearwardlyfrom the rear side of the hood andeach provided at its front'end with a depending attaching or coupling lug 12-, a cross piece 13 of substantially U-shaped form arranged in rear of said front arms and having the forwardly projectingbranches at its opposite ends connected with the rear ends of the front arms and a longitudinal rear arm 14 projecting posed between the attaching lug and the adj acent part of the hood so as to reduce to a minimum the metallic connection between the hood of the bracket and thereby avoid undue transmission of the heat of the electric light bulb through the metallic parts of the bracket to the adjacent surfaces of the piano. This transmission of heat is further reduced by providing the front parts of thebra'cket arms with openings 18 so as to allow air to pass through the same and keep them cool.

The rear parts of the front bracket arms are bent upwardly at right angles to the front: arts thereof so as to form outer jaws 19 which are adapted to face the outer or front side of the piano front while the cross piece of the bracket extends rearwardly over the top. of the piano front. In order to preventinarring' the outer side of the piano front and 'the upper edge thereof facings 20 of felt or other suitable cushioning material are applied to the rear side of the jaws 19a'i1d the undersides of the cjross piece 13 and "rear arm which permits these parts to engagewith the respective surfaces of the piano front without injuring ormarri'ng the same uponapplying the lamp thereto. The front and rear arms and the cross piece together with the front and rear lugs. are preferably construt'ited of a single piece of sheet metalto simplify the construction and reduce the cost'of manufacture.

21'representsa bow spring which is prejf; erably constructed of flat resilient metal and secured with the central part by means of rivets 22 to the rear lug of the bracket so that the ends thereof project forwardly and engage. piano ront. Owing to the resilience of these spring arms or ends'thesame'arecapable of adapting themselves to piano fronts which vary in thickness, thereby permitting of universal application of this lamp to.

pianos having an upright front board or any other piano having an upright member v capableofireceivin this mounting.

The bow spring w ich forms affl'exible jaw for engaging with the rear or inner sideof the piano front has its fiat sides arranged vertically and the same 1 extends horizontally and transversely with reference to the the same would ,be liable to interfere with bracket as a whole, so that whenthis spring engages with the rear side of the piano front the samewill not project downwardly into the space within the piano case where the mechanism therein.

'In applying this lamp to a piano it is onlynecessaryito spread the endsofthebow springapart sufiiciently to permit ofen agingthelfrontjaws with the outer side 0 the piano frontrand; the ends of the spring with the inner side of this front after which the resilience of this spring exerts a sufficient gripuponthepiano front to hold thelamp I reliably in place. The, mounting of the lamp and transversel mounted withuts central part on said ieldinglywith the inner side of the,

' pact and neat construction of this lamp the same when mounted on a piano does not detract from the appearance of the piano but rather enhances the same.

I claim as my invention:

1. A piano lamp comprising a hood adapted to receive an electric bulb and provided on its underside with a light outlet, and means for supporting saidhood on a piano front comprising a bracket connected with the hood and adapted to engage with the outer side of the piano front, and a horizontally arranged bow spring bracket and adaptedto engage its opposite ends with the inner side of the piano front.

2. A piano lamp comprising a hood I adapted to receive an electric bulb and providedonrits underside with a light outlet, and .means for supporting said hood on a piano front comprising a bracket having two front arms connected withthe hood and adapted to bearagainst the outer side of the piano front, a cross piece'conne'cting said front arms and extending over the piano front and a rear arm jpro 'ecting rearwardlyjfrom thecentralpart of said cross piece, and a springarranged on said rear m andadapted to, engagewith the inner side of the piano front;

3. A piano lamp 'COIHPIlSiIlg a hood adapted to receive'an"electricbulb and pr0-.

vided on its underside with a light outlet, means for supporting said -hood on a piano "from comprising a bracket having twospaced front armswhich are connected at their front ends with the rear side of said hood and which are providedat their rear ends with upwardly projecting jaws adaptedtofengage with the outer side of the "piano front,a u-shaped-cross piece having i'tsfends connected with said jaws and adapted to extend rearwardly over the" top of the piano front and a rear arm extending rear'wardly from the centralpart of said crosspiece and provided at its rearend with a downwardly projecting lug, and a bow spring secured with its central part to s'aid'lu andadapted'to engage'its opposite ends 'wlth the inner side of the iano front.
